Better AIM Field Of View Auto Adjust

When you start shooting your field of view will change to 90 so you can aim better. When you stop shooting your fov will be changed to 105 to see better what happens around you.

seta cg_fov "105"
set shooton "+attack;cg_fov 90;set vstr shootoff"
set shootoff "-attack;cg_fov 105;set vstr shooton"
bind MOUSE1 "+vstr shooton shootoff"



Seems good but not working on me :( anything to recommend?
